A FedEx label looks dense at first glance, but the parts that matter for billing are easy to find. The most important thing to understand is what the weight on the label does — and doesn’t — tell you about your invoice.
The main parts of a FedEx label
Sender and recipient
The “ship from” and “ship to” blocks. The recipient address is the one to double-check: a wrong suite number or ZIP code causes delays and can add an address-correction charge. Include a phone number, especially for international shipments.
Tracking number and barcodes
The tracking number appears as digits and as barcodes that FedEx scans through its network. Save the tracking number before handing over the package, and never cover the barcodes with tape.
Service
The service you booked (for example Ground, 2Day or Standard Overnight) is printed on the label. Check that it matches what you meant to buy.
Reference fields
Optional references such as a PO number or order ID. They don’t affect routing but make reconciling invoices much easier.
Weight
The weight printed on the label is the weight you or your shipping software entered when the label was created. It is not necessarily what you’ll be billed for.
FedEx bills the greater of the actual weight and the dimensional weight: length × width × height in inches ÷ 139, rounded up to the next pound (FedEx). If FedEx measures your package in its network and gets a higher billable weight than you entered, the difference shows up as an adjustment on your invoice, not on the label you printed.
The DIM weight surprise
The most common way it happens:
- You weigh the package: 8 lb, and create the label at 8 lb.
- The packed box measures 18 × 14 × 10 in.
- DIM weight: 2,520 ÷ 139 = 18.1 → 19 lb.
- You’re billed for 19 lb, not 8.
That isn’t a billing error — it’s the formula applied to the real box. Enter the dimensions when you create the label, calculate the DIM weight yourself first, and round every fraction of an inch up.
Surcharges that follow from the label
A residential delivery address adds a surcharge. FedEx’s 2026 list amounts are $6.95 per package for U.S. package services and $6.45 for FedEx Ground / Home Delivery, plus a delivery area surcharge in some ZIP codes ($6.60 residential, $8.80 extended residential) (FedEx 2026 surcharges). Mark commercial addresses correctly.
Three quick checks before handing over a package
- Recipient address. Check the street, suite and ZIP code.
- Service. The service on the label matches what you meant to book.
- Weight and dimensions. The dimensions you entered match the packed box, rounded up to whole inches.
International labels
International shipments also need customs information — contents, value, country of origin and tariff codes. In metric, dimensional weight is (L × W × H in cm) ÷ 5,000, rounded up to the next kilogram; in inches FedEx uses the same 139 divisor.
The takeaway
The label shows what you told FedEx. The invoice shows what FedEx billed. Calculate dimensional weight before you create the label and the two will match.
